TECHNICAL FIELD

The disclosure relates to the field of communications, and particularly to a beam measurement method, a terminal and a network device.

BACKGROUND

Along with the continuous development of wireless communication technology, requirements of a wireless communication system on coverage and wireless bandwidths for transmission have gradually increased and the wireless communication system may ensure coverage capabilities of networks through a beamforming technology.

The beamforming technology refers to an antenna array-based signal preprocessing technology that generates a directional beam by adjusting a weighting coefficient of each array element in an antenna array to obtain a significant array gain. In the beamforming technology, after a terminal accesses a cell, a network device to which the cell belongs allocates a beam suitable for data transmission of the terminal for the terminal.

However, in a related art, when a terminal in a connected state moves, the terminal is configured only on the basis of a measurement result of a cell, and thus it is unable to fully consider various factors during configuration.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the disclosure will be clearly and completely described below in combination with the drawings in the embodiments of the disclosure. It is apparent that the described embodiments are not all embodiments but part of embodiments of the disclosure. All other embodiments obtained by those of ordinary skill in the art on the basis of the embodiments in the disclosure without creative work shall fall within the scope of protection of the disclosure.

It is to be understood that the technical solutions of the embodiments of the disclosure may be applied to various communication systems, for example, a Global System of Mobile Communication (GSM), a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS) sytem, a Long Term Evolution (LTE) system, a Wireless Local Area Network (WLAN) system, a Public Land Mobile Network (PLMN) system and a 5th-Generation (5G) New Radio (NR) system.

It is also to be understood that a terminal may also be called User Equipment (UE), may also be called a mobile terminal, a mobile device and the like and may communicate with one or more core networks through, for example, a Radio Access Network (RAN). The UE may be a mobile terminal, for example, a mobile phone (or called a “cellular” phone) and a computer with a mobile terminal function. For example, the terminal may also be a portable, pocket, handheld, computer-embedded or vehicle-mounted mobile device and performs language and/or data exchange with the RAN.

It is also to be understood that a network device may be a device configured to communicate with the terminal. The network device may be an AP in the WLAN system, a Base Transceiver Station (BTS) in the GSM or the CDMA system, may also be a NodeB (NB) in the WCDMA system, and may further be an Evolutional Node B (eNB or eNodeB) in the LTE system, or a relay station or AP, or a vehicle-mounted device, a wearable device, a network device in a future 5G network system, a network device in a future evolved PLMN system or the like.

In addition, a cell involved in the embodiments of the disclosure may refer to the concept of a cell in an existing cellular network and may also be the concept based on an AP, a transmission point or a base station. There are no limits made thereto in the embodiments of the disclosure.

For convenient comprehension, an application scenario of a beam measurement method according to the embodiments of the disclosure will be introduced at first.

FIG. 1 is a schematic diagram of an application scenario of a beam measurement method according to an embodiment of the disclosure. From the application scenario illustrated in FIG. 1, it can be seen that in a cell, there may exist a beam (not illustrated in FIG. 1) configured for signaling transmission of a control channel and multiple beams (referring to beam 1 and beam 2 in FIG. 1) configured for data transmission of a data channel. That is, in the cell, the whole cell may be covered by a “wide beam” configured for signaling transmission of the control channel and the whole cell may be covered by multiple “narrow beams” configured for signaling transmission of the data channel.

FIG. 2 is a schematic diagram of another application scenario of a beam measurement method according to an embodiment of the disclosure. From the application scenario illustrated in FIG. 2, it can be seen that in the cell, there may exist multiple “narrow beams” (referring to beam 1 and beam 2 in FIG. 2) configured for control signaling transmission of a control channel and there may also exist multiple “narrow beams” (referring to beam 3 and beam 4 in FIG. 2) configured for data transmission of a data channel. A terminal 1 may perform control signaling interaction with a network device through the beam 2, the terminal 1 may perform data transmission with the network device through the beam 3, a terminal 2 may perform control signaling interaction with the network device through the beam 1 and the terminal 2 may perform data transmission with the network device through the beam 4. That is, the terminals may perform signaling interaction with the network device through the “narrow beams” configured for control signaling transmission of the control channel. The terminals may also perform data transmission with the network device through the “narrow beams” configured for data transmission of the data channel. The beams configured for control signaling transmission of the control channel between the terminals and the network device and the beams configured for data transmission of the data channel between the terminal and the network device may be the same and may also be different. It is to be understood that FIG. 2 only illustrates the condition that the beams configured for control signaling transmission of the control channel between the terminals and the network device are different from the beams configured for data transmission of the data channel between the terminals and the network device as an example.

It is to be noted that signal quality and/or signal strength for signal transmission between the terminal and the network device may be improved by use of a relatively high beamforming gain of a “narrow beam” relative to a “wide beam”. FIG. 3 is a schematic flowchart of a beam measurement method 300 according to an embodiment of the disclosure. The method 300 is executed by a terminal. It is to be understood that the terminal may be a terminal in a connected state, that is, a Non-Access Stratum (NAS) or Access Stratum (AS) signaling connection is established between the terminal and a network-side device. The method 300 may include the following operations.

In S310, the terminal receives measurement configuration information sent by a network device, the measurement configuration information being configured to indicate a parameter used during measurement of at least one beam.

Specifically, the measurement configuration information may include at least one of an indication of the beam, an indication of a beam group to which the beam belongs, an indication of a cell corresponding to the beam, an indication of an AP corresponding to the beam, an indication of a base station corresponding to the beam, a measurement frequency, a measurement cycle, a measurement duration, a measurement-mode, a beam resource related parameter or information of a reference signal corresponding to the beam.

The information of the reference signal corresponding to the beam may include a non-UE specific reference signal corresponding to the beam and/or a UE specific reference signal corresponding to the beam.

The information in the measurement configuration information may be related to the beam, for example, the indication of the beam, the indication of the beam group, the beam resource related parameter (for example, time-frequency resources or antenna port for sending the beam), the non-UE specific reference signal corresponding to the beam and the UE specific reference signal corresponding to the beam. The information in the measurement configuration information may also be unrelated to the beam, for example, the indication of the cell, the indication of the AP, the indication of the base station, the measurement frequency, the measurement cycle, the measurement duration and the measurement mode.

It is to be understood that the beam, the beam group, the cell, the AP and the base station are based on different levels. For example, the measurement configuration information may be a parameter applicable to one or multiple beams, and then the indication in the measurement configuration information may be an indication/indications of the one or multiple beams. For another example, the measurement configuration information may be a parameter applicable to all beams in one or multiple cells, and then the indication in the measurement configuration information may be an indication/indications of the one or multiple cells. Similarly, the measurement configuration information may be for a beam group (for example, beams in a cell may be divided into one or multiple beam groups), AP or base station, and correspondingly, the indication in the measurement configuration information may be an indication/indications of the one or multiple beam groups, an indication/indications of one or more APs, an indication/indications of one or more base stations, and the like. There are no limits made thereto in the embodiment of the disclosure.

All of the information, listed above, in the measurement configuration information is optional and part of information may be specified through a protocol or exchanged through other signaling. For example, when the measurement configuration information may be applied to multiple beams, since a measurement duration is related to a sweeping duration of a beam, a measurement duration of each beam in a system may be the same, the measurement duration may be specified in the protocol or set to be a default value and the measurement configuration information may include no measurement duration. For another example, the measurement mode may include the measurement duration and/or the measurement cycle, and then the measurement configuration information may include no measurement duration and/or no measurement cycle. For another example, the measurement frequency forms a certain mathematical relationship with the measurement cycle, and then the measurement configuration information may only include one of the measurement frequency and the measurement cycle. The information in the measurement configuration information will not be elaborated one by one herein.

It is to be understood that the information in the measurement configuration information may be the information per se and may also be indexes, serial numbers or the like available for indicating the information contents. There are no limits made thereto in the embodiment of the disclosure.

In S320, the terminal performs measurement of the at least one beam to obtain a measurement result according to the measurement configuration information.

Specifically, the at least one beam may be a beam configured for signaling transmission of a control channel and/or a beam configured for data transmission of a data channel. The beam configured for signaling transmission of the control channel and the beam configured for data transmission of the data channel may be the same beam. The beam configured for signaling transmission of the control channel and the beam configured for data transmission of the data channel may also be different beams.

For example, the measurement configuration information is a parameter applied to one or multiple beams. The at least one beam may correspond to one measurement configuration information. For example, the at least one beam measured by the terminal may include a beam 1, a beam 2 and a beam 3. The beam 1, the beam 2 and the beam 3 may correspond to a measurement configuration information, that is, the measurement configuration information may include a beam indication of the beam 1, a beam indication of the beam 2 and a beam indication of the beam 3. When the measurement configuration information is at least one measurement configuration information, the at least one beam may form a one-to-one correspondence with the at least one measurement configuration information, that is, each measurement configuration information may include a beam indication of a beam to be measured. The condition that the measurement configuration information is applied to one or multiple cells, beam groups, base stations or APs is similar to the condition that the measurement configuration information is applied to one or multiple beams, which will not be elaborated herein.

In at least one embodiment, the at least one beam may belong to the same cell. For example, when the at least one beam includes multiple beams, the multiple beams may form a beam group, and the beams of the beam group may be beams of a cell or part of beams of the same cell.

In at least one embodiment, the at least one beam may also belong to different cells respectively. For example, when the at least one beam includes multiple beams, part of beams in the at least one beam may belong to the same cell (for example, a first cell) and the beams, except the beams belonging to the first cell, in the at least one beam may belong to another cell (for example, a second cell). The first cell may be an adjacent cell of the second cell.

In the embodiment of the disclosure, when the at least one beam belongs to different cells, particularly belongs to a serving cell and an adjacent cell of the serving cell, beams of the adjacent cell may be measured to provide reference in advance and guarantee for mobility of the terminal.

In at least one embodiment, the at least one beam may include beams in the serving cell of the terminal and the beams of the adjacent cell of the serving cell.

In at least one embodiment of the disclosure, the measurement result includes signal strength and/or signal quality for each beam in the at least one beam. In an alternative embodiment, the measurement result includes signal strength and/or signal quality for the beam group to which the beam belongs. In an alternative embodiment, the measurement result includes signal strength and/or signal quality for the cell containing the beam. In an alternative embodiment, the measurement result includes an ordering of the signal strength and/or signal quality of the at least one beam.

Specifically, the signal strength and/or signal quality for the beam group to which the beam belongs may be signal strength and/or signal quality of a beam with optimal signal strength for signal transmission in the beam group and/or of a beam with optimal signal quality for signal transmission in the beam group, or may be average strength (or weighted average strength) and/or average signal quality (or weighted average quality) for all beams in the beam group, and the like. The signal strength and/or signal quality for the cell containing the beam may be signal strength and/or signal quality of a beam with optimal signal strength for signal transmission in the cell and/or of a beam with optimal signal quality for signal transmission in the cell, or may be average strength (or weighted average strength) and/or average signal quality (or weighted average quality) for all beams in the cell, and the like. The ordering of the signal strength and/or signal quality of the at least one beam may be an ordering, obtained according to the signal strength and/or the signal quality, of an index of the at least one beam.

In at least one embodiment, the measurement result may include an indication of a beam group or indication of a cell with optimal beam signal strength and/or optimal beam signal quality for signal transmission in the beam groups to which the beams belong or in the cells corresponding to the beams. In an alternative embodiment, the measurement result may include average signal strength and/or average signal quality for signal transmission in the beam groups to which the beams belong or in the cells corresponding to the beams.

Specifically, the measurement result may include information obtained by comparing or calculating the signal strength and/or the signal quality. For example, when the at least one beam belongs to multiple beam groups or multiple cells, signal strength and/or signal quality for signal transmission of the multiple beam groups or the multiple cells may be calculated at first, the beam group and/or cell with optimal signal strength and/or optimal signal quality for signal transmission is selected and an indication of the beam group or an indication of the cell is determined as the measurement result.

In S330, the terminal sends the measurement result to the network device.

According to the beam measurement method of the embodiment of the disclosure, the terminal receives the measurement configuration information sent by the network device and measures the beam according to the measurement configuration information to obtain a more accurate beam-based measurement result, so that the network device performs more efficient configuration for the terminal according to the measurement result.

In at least one embodiment, after the operation in S330, the method 300 may further include the following operation. The terminal receives a determination result sent by the network device. The determination result includes at least one of a target beam, a target beam group or a target cell determined by the network device according to the measurement result. The target beam is a beam on which the terminal may camp, the target beam group is a beam group on which the terminal may camp and the target cell is a cell on which the terminal may camp. A specific process for obtaining the determination result by the network device will be described in detail in the following method 400.

The measurement mode in the embodiment of the disclosure will be introduced below in detail. Information of the measurement mode may include at least one of information of the measurement duration or information of the measurement cycle. It is to be understood that a measurement mode includes a measurement duration and a measurement cycle. Part of contents may be specified in the protocol or exchanged through the other signaling.

In at least one embodiment, when the at least one beam belongs to one or multiple cells, the measurement duration may be a duration corresponding to measurement of all beams in the one or multiple cells. The measurement duration and the measurement cycle may be determined by the network device according to a sweeping cycle of all beams in the one or multiple cells and/or a sweeping duration of all beams in the one or multiple cells.

Specifically, FIG. 4 is a schematic diagram of a measurement mode according to an embodiment of the disclosure. FIG. 4 illustrates a cell, the cell includes four beams, i.e., a beam 1, a beam 2, a beam 3 and a beam 4, and a position of a reference signal used during measurement of each beam is illustrated in the figure. The measurement duration is a duration corresponding to measurement of the four beams in the cell, and the measurement cycle is the time elapsed from start of the present measurement to start of the next measurement (or from end of the present measurement to end of the next measurement). The measurement duration and the measurement cycle both may be determined based on the sweeping cycle of any beam and/or a sweeping duration of any beam.

It is to be understood that, when the at least one beam to be measured belongs to multiple cells and positions of reference signals for the beams in the multiple cells are suitable for measurement of all the beams during a measurement (for example, the positions of the reference signals for all the beams are concentrated in a certain region), the measurement mode of the embodiment may also be adopted. There are no limits made thereto in the embodiment of the disclosure.

In at least one embodiment, when the at least one beam belongs to one or multiple cells, the measurement duration may be a duration corresponding to measurement of one beam in the one or multiple cells. The measurement duration and the measurement cycle may be determined by the network device according to the sweeping cycle of each beam in the one or multiple cells and/or the sweeping duration of each beam in the one or multiple cells.

In the embodiment of the disclosure, the terminal measures all the beams in a centralized period of time, and data or control signaling may be transmitted in other time. Therefore, the terminal is not required to be frequently switched between a measurement state and a normal working state.

Specifically, FIG. 5 is a schematic diagram of a measurement mode according to another embodiment of the disclosure. FIG. 5 illustrates a cell, the cell includes four beams, i.e., a beam 1, a beam 2, a beam 3 and a beam 4, and a position of a reference signal used during measurement of each beam is illustrated in the figure. The measurement duration is a duration corresponding to measurement of one beam (for example, the beam 1) in the cell, and the measurement cycle is the time elapsed from start of measurement of the present beam to start of measurement of a next beam (or from end of measurement of the present beam to end of measurement of the next beam). The measurement duration and the measurement cycle both may be determined based on the sweeping cycle of any beam and/or the sweeping duration of any beam.

It is to be understood that, when the at least one beam to be measured belongs to multiple cells and positions of reference signals for the beams in the multiple cells meet the condition that the positions of the reference signals for all the beams are uniformly distributed, the measurement mode of the embodiment may also be adopted. There are no limits made thereto in the embodiment of the disclosure.

In the embodiment of the disclosure, the terminal, after measuring a beam, switches back to the working state for transmission of the data or the control signaling. Therefore, transmission efficiency of the data or the control signaling may be improved.

In at least one embodiment, when the at least one beam includes multiple beams and the multiple beams belong to multiple cells, the measurement mode includes multiple measurement durations and/or multiple measurement cycles. The measurement durations and the measurement cycles are determined by the network device according to a sweeping cycle of each beam of each cell in the multiple cells and/or a sweeping duration of each beam of each cell in the multiple cells.

Specifically, FIG. 6 is a schematic diagram of a measurement mode according to another embodiment of the disclosure. FIG. 6 illustrates two cells, the cell 1 includes four beams, i.e., a beam 1, a beam 2, a beam 3 and a beam 4, and the cell 2 includes a beam 5. The position of a reference signal used during measurement of each beam is illustrated in FIG. 6. There are two measurement durations. The measurement duration 1 is a duration corresponding to measurement of two beams (the beam 1 and the beam 2) in the cell 1 and the beam 5 in the cell 2, and the measurement duration 2 is a duration corresponding to measurement of the beam 3 or beam 4 in the cell 1. There may also be two measurement cycles. The measurement cycle 1 is a cycle corresponding to the measurement duration 1 and the measurement cycle 2 is a cycle corresponding to the measurement duration 2.
